Our expertise, experience, and training are the foundation of our work today and position us for continued success in the future
Founded in 1959 SCHMELZMETALL AG has developed into a world leader in innovative production of precipitation hardened copper alloys.
Thrust chamber of Ariane 5 rocket. Schmelzmetall is since 1996 significantly participating on the developing of the alloy for the thrust chamber
Today SCHMELZMETALL group is a leading manufacturer of high performance alloys. SCHMELZMETALL is represented worldwide by its own subsidiaries and partners. Our HOVADUR® alloys stand for the highest quality at the most compe- titive price/performance ratio.
Based on over five decades worth of first hand expertise in vacuum system copper alloy production we guarantee the highest level of consistency and quality.
The proven capacity to process our product into semi finished and finished parts as well as the ability to apply our knowledge of alloy metallurgy serve as a unique advantage for our customers:
High performance alloys that possess precise properties for meeting specific individual requirements.
HOVADUR® high performance alloys: from raw metal to high quality finished product
Those HOVADUR® alloys manufactured by SCHMELZMETALL are smelted and casted in inductively heated vacuum furnaces. Thanks to this proprietary process, the alloys achieve the highest degree of purity, and acquire special technological properties. Our vacuum process also minimizes negative environmental impacts.

The basic materials for all alloys are pure metals such as copper, nickel, cobalt, and master alloys containing chromium, beryllium, zircon etc. The cast weight varies between 500 kg and 1500 kg. According to weight, the metal is cast in one or several moulds.
Our partner companies process the ingots into semi finished products through forging, rolling, extruding, and drawing.
Our mastering of the production process creates customer satisfaction through high quality deliverables
The processing to semi finished products is followed by a heat treatment which is necessary to achieve the required properties such as hardness and high thermal and electrical conductivity.
Special thread-core in moulds for screw-caps
After the heat treatment the semi finished products are tested for hardness and conductivity. We routinely apply non destructive test protocols such as ultrasonic and eddy current testing as part of our quality control.
HOVADUR® high performance alloys from SCHMELZMETALL are used worldwide
Our products are highly recommended for a variety of industrial applications and are indispensable in many sectors of modern industry.

Excellent electrical conductivity combined with the specific alloy's maximum hardness produces optimal welding conditions and guarantees the electrodes' high resistance to wear. Due to our proprietary processes our alloys are applied in a wide range of resistance welding techniques such as seam, spot, and cross-wire welding.
Casting-Technology: Light metal die casting and mould casting
HOVADUR® alloys are indispensable in foundry production due to their excellent thermal conductivity. SCHMELZMETALL's advanced manufacturing process provides greater resistance to fire cracking in all of its alloys and allows for the most efficient cooling cycle available.
Plastic injection moulds
SCHMELZMETALL’s HOVADUR® alloys provide an up to ten fold increase in thermal conductivity against other mould materials. This ensures the customer shorter work cycles, higher quality, and longer lasting moulds.
